systemd is a new system and service manager for Linux system, which was implemented/adapted into all the major Linux distributions over the traditional SysV init systems due to lots of issue/improvement has to be on SysVinit systems.
All the service files are available on /etc/init.d/ directory for SysVinit system.
For systemd system, the service files are available on /usr/lib/systemd/system/ directory.
If you would like to perform any kind of actions like start, stop, restart, enable, reload & status against the specific service then use the following commands.
Make sure that you should have admin privileges to run these commands except status command. It should be root or sudo permission needed to run the below commands.
What Is Network Manager?
NetworkManager is a dynamic network control and configuration system that attempts to keep network devices and connections up and active when they are available.
NetworkManager can be used to configure the following types of connections: Ethernet, wireless, mobile broadband (such as cellular 3G), and DSL and PPPoE (Point-to-Point over Ethernet).
